Getting Winamp to work with Dell Wireless Keyboard (Play, Stop, etc. features)

http://accessories.us.dell.com/sna/images/products/large/310-4170.jpg

Well first, for reference, I have that keyboard above. Now I installed Winamp 5.05 because I am not a big fan of MusicMatch at all. The only problem is I can no longer use the Play/Pause, Stop, Previous, and Next buttons on the keyboard with Winamp.  My question is, is there a specific plug-in for Winamp or driver for the keyboard that I need to have it work and work smoothly?

Thanks.
